HAY-PRESS.

Specification of Letters Patent.

Patented A 11 26,1913.

Application filed December 23, 1909. Serial No. 534,671.

To all whom it may concern:

Be it known that I, JonN OLSON, a citi- Zen of the United States,residing at Bradley, in the county of Kankakee and State of Illinois,have invented certain new and useful Improvements in Hay Presses, ofwhich the following is a specification, reference being had to theaccompanying drawings.

My invention relates to hay presses, and it has for its principal objectto provide certain improvements in presses operated by horsepower, suchmeans relating more particularly to the mechanism for feeding the hay tothe lialingchamber. I accomplish this object as illustrated in thedrawings and as hereinafter described.

l Vhat I regard as new is set forth in the claims.

In the accompanying drawings,Figure 1 is a plan view of my improvedpress; Fig. 2 a side elevation thereof; Fig. 3 is an enlarged detail,being a side elevation of part of the mechanism by which the feedingmechanism is operated; Fig. 4t is a perspective view of part of themechanism shown in Fig. 3; Fig. 5 is a longitudinal vertical sectionthrough the baling-case and adjacent parts; Figs. 6 and 7 are plan viewsof part of the mechanism for operating the plunger and feeding devices;and Fig. 8 is a detail, being a vertical section on line 8-8 of Fig. 1showing the feeding or beater-arm and connected parts.

Referring to the drawings,9 indicates the frame of the machine, which ismounted on front and rear wheels 10-11, respectively, and at its rearend carries the usual baling-case 12. Said case contains a balingchamber13, the hay being introduced thereinto through a hopper let overlyingsaid baling-chamber, as shown in Fig. 5.

15 indicates a plunger which is adapted to reciprocate in the frame,moving back and forth in the baling-chamber so as to compress the haytherein in the usual way.

16 indicates the plunger-rod by which the plunger is reciprocated.

17 indicates a brace-rod, the rear end of which is connected to thebalingcase preferably by a stirrup 18, its front end being connected toa suitable bracket 19 connected in any suitable way with the front axle20.

21 indicates a cross-head mounted upon and keyed to a central pivot 22at the front of the frame 9, said pivot coinciding with the pivotalcenter of the front axle 20, said pivot also forming the pivot bolt forthe front axle 20. l

23 indicates a sweep-lever of the usual type connected. at its rear endwith a bracket 2 mounted upon and keyed to the pivot-bolt 22, and 25indicates a brace for the outer end of said lever, said brace beingconnected at its rear end with the bracket 2st at the opposite side ofthe pivot 22. The arrangement is such that as the team swings thesweep-lever 23 around the pivot 22 the cross-head 21 is correspondinglyrotated about said pivot.

As best shown in Figs. 6 and 7, the crosshead 21 is provided withanti-friction rollers 26 at its ends, and said rollers are adapted toengage a casting 27 provided at the forward end of the plunger-rod 16during the operative stroke of said plunger-rod. 28 indicates a linkwhich operates to hold the forward end of the plunger-rod in position tobe operated upon by one arm or the other of the cross-head, said linkbeing pivotally connected at its outer end by a pivot 29 with thecasting 27, and being journaled at its inner end upon the pivot bolt 22.When the plunger-rod is in its retracted position, as shown in Fig. 6,the casting 27 is in position to be engaged by one of the rollers 26 ofthe cross-head and is held in position to be so operated upon by thelink 28.

Assuming the parts to be in the position shown in Fig. (3, when thecross-head 21 rotates in the direction indicated by the arrow in saidfigure the roller 26 which is in engagement with said casting operatesto move the plunger-rod endwise toward the haling-case, moving out ofengagement with the casting 27 as the operation continues, as shown inFig. 7. As the plunger-rod moves longitudinally as described, afterpassing the point shown in Fig. 7 it swings gradually into alinementwith the frame of the machine and with the cross-head 21 so that thegreatest power is applied to the plunger-rod toward the end of itsstroke, which is the time of greatest compression. As soon as theplunger reaches the point of greatest compression, the cross-head 21disengages the casting 27 and the plunger rebounds, but in order toinsure the return of the plunger to the limit of its forward movement arocking-arm 30 is provided which is pivoted at 31 upon the frame 9adjacent to the path of the rollers 26, the outer end of said arm beingconnected by a link 32 with the inner portion of the plunger-rod 16, asshown at 33 in Figs. 6 and 7. The inner end of the arm 30 carries afinger 34 which lies in the path of the rollers 26, except when theplunger-rod is at its extreme forward position. Consequently, after oneor the other of the rollers 26 disengages the casting 27, it moves intoengagement with the finger 34, and as it continues to travel operatesthrough said finger to rock the arm 30 to the right, as shown in Fig. 6,and thereby carry the plunger-rod 16 forward to the limit of itsmovement in that direction. Thus I provide a positive return movementfor the plunger as well as a positive compressing movement.

The hay is fed into the baling-chamber from the hopper 14 by means of arocking beater-arm 35 having a head 36 which swings down through thehopper into the baling-chamber, as shown in Fig. 5. The beater-arm 35,which is preferably composed of two members spaced apart and held bycross-bolts 37, is pivotally mounted at its forward end upon a shaft 38which is supported by brackets 39 mounted on the baling-case in front ofthe hopper 14, as best shown in Fig. 5,the members of the beaterarmbeing suitably shaped so that as the beater-arm is swung about the shaft38 the beater-head is moved up and down through the hopper into and outof the baling-chamher. The shaft 38 is rocked to operate the beater-armby means of a cranlcarm 39 secured to said shaft and projectingclownwardly and rearwardly therefrom, said crank being connected by alink 40 to one arm 41 of a bell-crank lever 42 mounted on a pivot 43 atone side of the baling-case, as shown in Figs. 5 and 8. The other arm 44of said bell-crank lever is connected by a connecting-rod 45 with arocking-lever 46 mounted at the front of the frame 9 on a pivot 47supported by a bracket 48, as best shown in Figs. 6 and 7. The pivot 47is placed between the ends of the lever 46, the rear end of said leverbeing provided with a curved projection 49 which, when the lever 46 isin the position shown in Fig. 6, lies in the path of the rollers 26,being adjacent to the finger 34. It will be noted that when the partsare in the position shown in Fig. 6 the connecting-rod 45 is more nearlyparallel with the lever 46, and consequently the connecting-rod 45 is inits rearmost position. At this time the arm 44 of the bell-crank leveris in a substantially vertical position and the arm 41 in a horizontalposition, thus lifting the arm 39 and holding the beater-arm in itsuppermost or inoperative position,- the beater-head 36 being then abovethe hopper 14. By rocking the lever 46 to the position shown in Fig. 7the connectingrod 45 will be drawn forward, thereby moving thebell-crank lever 42 to the position shown in Figs. 5 and 8, and movingthe beaterhead down into the baling-chamber, as shown in said figures.This operation necessarily takes place while the plunger is retracted,and to secure the proper timing of the operations of the plunger andheaterarm the projection 49 of the lever 46 is arranged to be engaged bythe rollers 26 as soon as they operate through the finger 34 to move theplunger-rod forward to the limit of its movement in the mannerdescribed. This is clearly shown in Fig. 6, from which it will be seenthat the roller 26 engages the projection 49 as it moves out ofengagement with the finger 34. Then the parts are in the position shownin Fig. 6, as the crosshead 21 continues to rotate the roller 26 inengagement with the projection 49 will operate to move outward theforward end of the lever 46, rocking the same about its pivot 47 andpulling back on the connecting-rod 45, with the result of moving thebeaterhead down into the hopper and balingchamber in the manner abovedescribed.

In order to restore the beater-arm and head to their uppermost orinoperative position, a lever 50 is provided which is pivotally mountedat 51 upon a bracket 52 secured at one side of the frame 9, as shown inFig. 6. The forward end of the lever 50 is curved, as shown at 53 inFigs. 4, 6 and 7, its rear end being provided with a slot 54 whichreceives a pin 55 carried by the forward end of the lever 46. TVhen theparts are in the position shown in Fig. 7, the forward end of the lever50 lies in the path of the rollers 26, the arrangement being such thatimmediately after either of the rollers 26 disengages the lever 46 itcomes into engagement with the lever 50, pressing the forward end ofsaid lever outward and moving its rear end inward, thus swinging theforward end of the lever 46 inward and moving said lever more nearlyinto alinement with the connecting-rod 45. From the foregoingdescription it will be seen that such rocking of the lever 46 rocks thebell-crank lever 42 to swing the crank 39 upward, consequently movingthe beaterarm and head up out of operative position. The operation ofmoving the beater-head out of operative position is assisted by theaction of the arm 30 upon the rear or inner end of the lever 46. As bestshown in Fig. 7, when the plunger has been moved part way back on itscompressing stroke the arm 30 comes in contact with the inner end of thelever 46, which lies in its path, and as the plunger continues itsmovement said arm carries the inner end of the lever 46 back, therebycontinuing the rocking movement initiated by the action of the lever 50upon the lever 46. The arrangement is such that when the roller 26passes out of engagement with the lever 50 the arm 30 continues to pressbackward the inner end of the lever 46, thus giving a more positive andcontinuous application of power to restore the beatenhead to itsinoperative position,

In order to close the bottom of the hopper when the plunger is in thebaling-chamber and thereby permit a fresh charge of hay to be placed inthe hopper Without waiting until the plunger is withdrawn, the plunger15 is provided on its upper side with a hinged-plate 56,. which extendsforwardly therefrom, forming an extension of the upper surface of theplunger, its outer edge being supported by an arm 57 carried by aswinging link 58, the rear end of which is pivoted to a bracket 59 whichprojects forwardly from the front side of the hopper 14. By thisconstruction when the plunger advances the plate 56 swings down into thesame plane as the upper surface of the plunger and forms an extensionthereof which closes the bottom of the hopper during the compressionstroke and thereby enables the operator to place a fresh charge of hayin the hopper without waiting until the plunger is withdrawn. Upon thewithdrawal of the plunger the plate 56 swings up out of. the way, asshown .in the drawings.

By the construction described the feeding mechanism is not operated tocarry the hay down into the bailing-chamber until after the plunger hasbeen carried forward to the limit of its movement in that direction,thus giving ample time for the placing of a fresh charge of hay in thehopper, and when the feeding mechanism is operated it is quickly movedout of operative position so as not to interfere with the operation ofthe plunger on its compression stroke. The return movement of thefeeding mechanism is much quicker than its downward movement, so thatmore time is allowed for placing a fresh charge of hay in the hopper.
